By applying the technical proposal of the utility model, the pot body comprises a shell 10, an inner pot 20, a heating element 30 and a lifting component 40. When the heating element 30 is located at the ascending position, the locking element 43 is located at the locking position, the driving element 41 drives the shifting element 42 to rotate, the first shifting lever 421 revolves around the rotation axis of the shifting element 42, when the first shifting lever 421 rotates to the position abutted to the locking element 43, the first shifting lever 421 drives the locking element 43 to move to the unlocking position separated from the transmission element 44, and under the influence of the self gravity of the heating element 30, the heating element 30 moves downwards relative to the casing 10 until the heating element 30 moves to the descending position separated from the bottom wall of the inner pot 20, so that the heat conducted from the heating element 30 to the inner pot 20 is reduced after cooking is completed. When the heating element 30 is located at the descending position, the driving element 41 drives the stirring element 42 to rotate, the second driving lever 422 revolves around the rotating axis of the stirring element 42, when the second driving lever 422 rotates to the position abutted to the driving element 44, the second driving lever 422 drives the heating element 30 to move upwards relative to the shell 10 through the driving element 44, when the heating element 30 moves to the ascending position attached to the bottom wall of the inner pot 20, the locking element 43 is located at the locking position to be locked with the driving element 44, the heating element 30 is attached to the bottom wall of the inner pot 20, the heating element 30 conducts heat to the inner pot 20, and the pot body cooks. In addition, the driving cooperation of the toggle piece 42 to the locking piece 43 and the transmission piece 44 can control the vertical movement of the heating piece 30, and the locking piece 43 can lock the heating piece 30 at the lifting position when the heating piece 30 is at the lifting position, so that the position of the heating piece 30 is kept without the continuous power supply of the driving piece 41, and the service life of the driving piece 41 can be prolonged. With the above structure, since the heating element 30 is kept at the ascending position, the gravity of the heating element 30 is transmitted to the locking member 43 through the transmission member 44, the toggle element 42 and the driving element 41 are not stressed, so that the lifting assembly 40 adopts the mechanical toggle element 42 and the locking member 43, the heating element 30 is locked at the ascending position, the damage of the driving element 41 adopting an electric device is avoided, and the service life of the lifting assembly 40 is prolonged as the mechanical structure is not easy to damage compared with the electric device itself.

The shifting member 42 has a first shifting lever 421 cooperating with the locking member 43 and a second shifting lever 422 cooperating with the transmission member 44, and includes the following two structures:

the first one is that the first driving lever 421 and the second driving lever 422 adopt an integrated structure, the first driving lever 421 and the second driving lever 422 are located on different vertical surfaces, the first driving lever 421 and the second driving lever 422 are driven to coaxially rotate by the driving part 41, and a vertical circular surface formed by the rotation of the first driving lever 421 is not overlapped with a vertical circular surface formed by the rotation of the second driving lever 422;

secondly, the first driving lever 421 and the second driving lever 422 adopt a split structure, the first driving lever 421 and the second driving lever 422 are located on the same vertical plane, the driving member 42 includes a first gear, a second gear and a third gear, the second gear is meshed with the first gear, the third gear is meshed with the first gear, the second gear and the third gear are respectively arranged on two sides of the driving member 44, the second gear is provided with the first driving lever 421, the third gear is provided with the second driving lever 422, the first gear is driven to rotate by the driving member 41, the first gear drives the second gear and the third gear to rotate by meshing transmission, so that the first driving lever 421 rotates around the axis of the second gear, the second driving lever 422 rotates around the axis of the third gear, the rotation axis of the first driving lever 421 and the rotation axis of the second driving lever 422 are parallel to each other and do not coincide with each other, and the vertical circular plane formed by rotation of the first driving lever 421 and the vertical circular plane formed by rotation of the second driving lever 422 are coplanar.

In the present embodiment, the first structure is adopted, so that the transmission structure between the driving element 41 and the toggle element 42 can be simplified, and the first toggle lever 421 and the second toggle lever 422 rotate coaxially, so as to ensure the synchronous independence of the first toggle lever 421 and the second toggle lever 422 on the driving action of the locking element 43.

As shown in fig. 3, 13, 14, 18 and 22, in the present embodiment, the locking member 43 is rotatably disposed on the housing 10 about a horizontal axis thereof, the first shifter 421 and the second shifter 422 are both vertically disposed, the driving member 41 can drive the shifter 42 to rotate about the horizontal axis thereof, and the first shifter 421 and the second shifter 422 are located on different vertical planes. With the above structure, when the driving element 41 drives the dial 42 to rotate around the horizontal axis thereof, the first shift lever 421 and the second shift lever 422 are both vertically disposed on the dial 42, so that the first shift lever 421 and the second shift lever 422 revolve around the rotation axis of the dial 42, the rotation surfaces of the first shift lever 421 and the second shift lever 422 are both vertical circular surfaces, and the rotation surfaces are perpendicular to the rotation axis of the dial 42. Because the retaining member 43 is rotatably disposed on the housing 10 around the horizontal axis thereof, when the first driving lever 421 rotates to the position abutting against the retaining member 43, the first driving lever 421 drives the retaining member 43 to rotate around the horizontal axis of the retaining member 43 relative to the housing 10, the retaining member 43 rotates to the unlocking position separated from the transmission member 44, and because the first driving lever 421 and the second driving lever 422 are located on different vertical surfaces, in the rotating process of the driving member 42, the vertical circular surface formed by the rotation of the second driving lever 422 does not intersect with the space where the retaining member 43 is located, the second driving lever 422 does not contact with the retaining member 43, and the second driving lever 422 cannot drive the retaining member 43 to rotate, so that the retaining member 43 is only matched with the first driving lever 421, and the retaining member 43 is ensured to rotate only under the driving of the first driving lever 421.

As shown in fig. 3, 13, 14, 18 and 22, the locking member 43 is located between the transmission member 44 and the toggle member 42, and the length of the first toggle lever 421 is smaller than the length of the second toggle lever 422.
